Here is How to display current CryptoCurrency prices on a WordPress website without using any plugins.
Add these snippets to the functions.php file of your active theme and then add the shortcode where you want to display the content.
Bitcoin Price
This snippet uses the CoinDesk API to retrieve the current Bitcoin price:
function bitcoin_price_shortcode() {
$response = wp_remote_get( 'https://api.coindesk.com/v1/bpi/currentprice.json' );
$data = json_decode( wp_remote_retrieve_body( $response ), true );
$price = $data['bpi']['USD']['rate'];
return $price;
}
add_shortcode( 'bitcoin', 'bitcoin_price_shortcode' );
Then just add the [bitcoin] shortcode anywhere you want to display the price, for example:
The current Bitcoin price is $[bitcoin]
You can also change the currency in the code above from USD to EUR.
Etherium Price
This snippet uses the CryptoCompare API to retrieve the current Ethereum price:
function eth_price_shortcode() {
$response = wp_remote_get( 'https://min-api.cryptocompare.com/data/price?fsym=ETH&tsyms=USD' );
$data = json_decode( wp_remote_retrieve_body( $response ), true );
$price = $data['USD'];
return $price;
}
add_shortcode( 'ethereum', 'eth_price_shortcode' );Add the [ethereum] shortcode anywhere you want to display the price, for example:
The current Ethereum price is $[ethereum]

$data = json_decode( wp_remote_retrieve_body( $response ), true );
$output = '<ul>';

$name = $crypto['CoinInfo']['FullName'];
$price = $crypto['RAW']['USD']['PRICE'];
$output .= '<li>' . $name . ': $' . $price . '</li>';
}
$output .= '</ul>';
return $output;
}
add_shortcode( 'top5', 'top_cryptos_shortcode' );
